Story

Transformation of a Farmhouse

Revitalizing an 18th-century farmhouse in Grandvillard In the heart of Grandvillard, Bard Yersin Architectes undertakes the transformation of an 18th-century farmhouse, introducing three new apartments while respecting the building's historical essence. The original farmhouse, characterized by its large unifying roof and structural bays, is reimagined to accommodate modern living without losing its typological roots. The project restores a previously removed dwelling, transforming the extended rural area into an intermediate space that serves as both a porch and a covered terrace. The existing dwelling is renovated and expanded into the attic, while the hayloft, a significant spatial element, becomes the entrance hall for the new apartments. The reconstructed north facade maximizes light intake with expansive openings, adhering to the original pierced masonry logic. Inside, the plan follows traditional typological principles, with two structural cells subdivided into rooms. A central concrete wall enhances visual connectivity between major ground floor spaces, while upstairs, a windowless distribution hall is illuminated through the roof, echoing the volumetric form of old chimneys. The former stables now house two apartments, maintaining the domestic dimension suggested by the original south facade's moldings. The spatial organization respects the existing logic, with day spaces on the ground floor and bedrooms above, enriched by split-levels due to varying floor heights.
